Softball New Zealand's manager says it's with the help of experienced Pacific players.

Down 3-2 at the bottom of the sixth innings, New Zealand's Joel Evans slugged a home run out of left field with the bases loaded, giving the Black Sox a 6-4 lead heading into the final inning.

Softball New Zealand Manager, Glen Roff, says they owe a lot to their Pacific players.

"It's part of our success, having a heavy Maori and Pasifika influence over the years," he says. "They're hugely talented and it's played a big part in the history of New Zealand softball."

The team have won all of their 10 games since the tournament began on July 8, in Whitehorse Canada.

Roff says New Zealand should stand up and be proud.

"It's fantastic for us. We couldn't be more ecstatic for the team, for the boys, for the coaching staff and what they've achieved," he says.

Meanwhile, Softball New Zealand Chief Executive Tony Giles, says he hopes to see more money invested in the sport.

"Our playing group don't do it for the dollars or cents," he says. "These are amateur individuals that have full-time jobs and have taken five weeks of leave, unpaid, to go and represent their country."

Giles says it's a record-breaking win for New Zealand.

"No other sport in New Zealand has ever achieved seven world titles," he says. "For us to do it offshore in the Northern Hemisphere in Canada is just amazing."
